Description
Available records for the anime *Kasei Yakyoku* (*Nightsong of Splendor*) list characters including Sara Uchida, Akiko Hashou, Takao "Taka" Itou, and Kiyokuni Saionji. No reference exists for a figure titled "Marquess Hanyuu" within this series. The narrative centers on tragic romance amid 1923 Tokyo and the Great Kanto Earthquake, with no indication of such a character.
Separately, the term "Marquess" arises in unrelated contexts like Marquess Wen of Wei in Chinese history or European nobility discussions. The name "Hanyū" solely connects to a character in *Higurashi When They Cry*, unrelated to *Kasei Yakyoku*. No official *Kasei Yakyoku* media—seasons, films, OVAs, or spin-offs—includes this character.
